If approved, D-PLEX₁₀₀ would address a critical unmet medical need in the prevention of surgical site infections

PDUFA target action date currently planned for the first quarter of 2027

PETACH TIKVA, Israel, June 01, 2026 (GLOBE NEWSWIRE) -- PolyPid Ltd. (NASDAQ:PYPD) ("PolyPid" or the "Company"), an innovative biopharmaceutical company dedicated to improving patient outcomes by elevating treatment effectiveness, right where care begins, today announced the successful completion of its New Drug Application ("NDA") submission on a rolling review basis to the U.S. Food and Drug Administration ("FDA") for D-PLEX₁₀₀, the Company's lead product candidate for the prevention of surgical site infections ("SSIs") in patients undergoing colorectal surgery. The Company anticipates a potential FDA decision in the first quarter of 2027 under the Prescription Drug User Fee Act ("PDUFA") review timeline.

The NDA is supported by positive results from the Company's pivotal Phase 3 SHIELD II trial that met its primary endpoint and all key secondary endpoints, and demonstrated a 60% relative risk reduction in SSIs compared to standard of care (p=0.0013). D-PLEX₁₀₀ has been granted Breakthrough Therapy, Fast Track, and Qualified Infectious Disease Product ("QIDP") designations by the FDA, supporting eligibility for Priority Review.

"Completing the NDA submission for D-PLEX₁₀₀ is a defining milestone for PolyPid and the culmination of years of disciplined clinical and regulatory work," said Dikla Czaczkes Akselbrad, Chief Executive Officer of PolyPid. "With the full application now before the FDA, we are focused on supporting the agency's review, finalizing our U.S. commercial partnership discussions, and preparing for the potential approval and launch of a novel approach to the prevention of SSIs."
